Electrical Requirement: 120V AC, 60Hz. 15A Branch Circuit.
The hood is equipped with an internal blower. It is not designed for use with a
remote blower.
The hood must be ducted to the outside. It is not designed for use with a recircula-
tion unit and/or charcoal filters.
For the most efficient air flow exhaust, use a straight duct run or as few elbows as
possible.
Do not use flex ducting. Always use metal ductwork with minimum diameter of 6".
A transition is necessary to connect to larger diameter ductwork or to square duct-
work.
COLD WEATHER installations should have an additional backdraft damper
installed to minimize backward cold air flow and a nonmetallic thermal break to
minimize conduction of outside temperatures as part of the ductwork. The damper
should be on the cold air side of the thermal break. The break should be as close
as possible to where the ducting enters the heated portion of the house.
Always install a metal vent cover where the ductwork exits the house.
Hood installation height above cooktop is the user's preference. The lower the
hood above the cooktop, the more efficient the capturing of cooking odors,
grease, and smoke. This hood has been approved for installations as low as 30"
and as high as 36" above the cooktop. The lower height may be inconvenient for
tall people and large cooking vessels.
In addition, the chimney sections, when fully extended, measure 42 3/4" tall. In
order for the upper chimney section to meet the ceiling, the highest allowable ceil-
ing height is 9 1/2' (assumes the hood is installed 36" above the cooktop).
Make-Up Air: Local building codes may require the use of make-up air systems
when using ducted ventilation systems greater than specified CFM of air move-
ment. The specified CFM varies from locale to locale. Consult your HVAC profes-
sional for specific requirements in your area.
Pull hood from outer packaging. Remove and discard all packaging materials.
Install one way damper as shown in Figure 1. If necessary, install transition, ther-
mal break and additional backdraft damper.
